Abstract: 1,224,450. Sorting spools with and without yarn remainder thereon. KNOTEX MASCHINEBAU G.m.b.H. 1 Feb., 1968 [2 June, 1967], No. 41367/70. Divided out of 1,217,211. Heading D1F.  In a device for separating spools having yarn residue from those without yarn residue, the spools are passed downwardly head first over a testing member 101 having upwardly directed bristles or hooks, or a blade 102 to arrest spools having yarn residue. In the embodiment shown the head of a spool is supported on and slides along a pair of spaced rails (104), 105. A feed arm 106 is then pivoted to move the spool into 'the dot-dash position shown, allowing a spool without yarn residue to slide down plate 108. Return pivoting of arm 106 causes end part 109 of rail 105 to shift so that a spool arrested by the testing member falls from between the rails. In a second embodiment a spool slides down a plate to stop adjacent the testing member. Retraction of the stop allows a spool without yarn residue to resume sliding while a spool held by the testing device is removed by an ejector.

Title: Improvements in or relating to magnetic transducing systems
IPC: G11B5/37
Filed: 1962-10-31
Abstract: 966,438. Magnetic transducers. AMPEX CORPORATION. Oct. 31, 1962 [Nov. 24, 1961], No. 41249/62. Heading G5R. Simultaneous recording and play-back of a pulse signal on a magnetic tape is effected by a single magnetic core transducer having a single non magnetic gap and a local circuit providing an output representative of the recording effected thereby. The core 10 (Fig. 1) is coupled via coil 14 to a balanced bridge circuit 12 comprising an inductance 20 and resistances 22 and 24. The input signal is applied at terminals 26 and recording on tape 18 occurs at gap 16 of the core 10. Magnetic flux developed in core 10 by this signal is negated by the balanced circuit 12 but the presence of the recorded signal on tap 18 causes a flux change in the area of gap 16 and at trailing pole 38 of the core thus inducing a current in coil 14. The output signal taken from terminals 28 thus represents the recorded signal on the tape. This system is applicable to RZ or NRZ pulse signals. An embodiment for particular application to RZ pulses is shown in Fig. 4 in which a battery 50, a diode 48 and a resistor 52 are connected in series across a coil 46. The battery provides a threshold voltage which is insufficient to render diode 48 conductive. On the introduction of a tape, pulse magnetised with the appropriate polarity to the vicinity of the gap, however, the diode conducts due to the increase in inductance. The output at terminals 54 thus determines whether or not a pulse has been effectively recorded on the tape. For use in NRZ recording an embodiment is described (Fig. 6, not shown) in which the core gap contains two Hall elements separated by an electric insulator. The output signal is obtained from a voltmeter positioned across the Hall elements. In a further arrangement for NRZ recording (Fig. 8 not shown) unipolar RZ pulses at a higher frequency than the NRZ pulses are superimposed on the latter so as to provide immediate detection of information loss.

Title: Pipeline leak detector
IPC: H01H19/63
Filed: 1966-09-16
Abstract: 1,121,824. Acoustic leak-detector. ESSO RESEARCH & ENGINEERING CO. 16 Sept., 1966 [14 Dec., 1965], No. 41551/66. Heading H4D. [Also in Division G1] Leaks in a pipeline conveying a moving fluid under pressure are detected by passing a tool carrying a directional microphone through the pipeline and sensing the level of received noise in a predetermined ultrasonic frequency range. It is stated that leak noise is predominantly in the ultrasonic range, and can thus be distinguished from background pipeline noise, which is mainly in the audio frequency range. In the Figure 1 embodiment the tool comprises a body 10 centralized in the pipeline and acoustically insulated from pipeline noise by sprung rollers 14 and carrying a microphone 26. Baffles 28 and 32 provide microphone 26 with a directional characteristic to give an abrupt change in received noise level as the tool passes a leak. Units carried in body 10 filter and analyse the microphone output and provide a record of the peak noise level in one or more ultrasonic frequency ranges. The presence of a leak is ascertained from the record and its position along the pipeline is obtained from an odometer record of the position of the tool along the pipeline. In an alternative embodiment of the tool (Fig. 2, not shown), the microphone and baffle assembly is disposed behind the sprung roller system and is flexibly Coupled thereto to permit the tool to negotiate curved pipelines. Noise analysis (Figs. 3, 4, 5, not shown).- The microphone output, filtered to remove audio frequencies is passed to parallel channels (Fig. 3 or 4) for analysis of adjacent ultrasonic frequency bands. In each channel the filtered signal is mixed with a swept frequency signal and the resulting side-band signals are passed through a band-pass filter to a demodulator which provides a D.C. voltage proportional to the peak signal level occurring during the frequency sweep. (For example, leak noise in the frequency range 65-85 kc. is analysed by using a swept frequency of 70-80 kc. and a 5 kc. band-pass filter). This voltage is recorded in a corresponding channel of a multichannel recorder. Alternatively (Fig. 5), a single demodulator may be used to record the peak level of the entire ultrasonic frequency range.

Title: Pituitary gonadotropic hormone preparation and method for its production
IPC: A61K38/24
Filed: 1963-10-23
Abstract: A pituitary gonadotropic hormone is obtained from menopausal or post-menopausal human urine by acidifying the urine to pH 4-4.5, adding thereto 0.5% by weight thereof of siliceous or diatomaceous earth and 1% by weight of kaolin and separating the solid by centrifugation after agitating for about an hour.  Thereafter, the solids are washed (using acidified water of pH about 4.5) and the active material removed therefrom by elution with 1M aqueous ammonia to give an eluate of pH 11 to 11.3.  This eluate is adjusted to pH 8.5 to give a precipitate which is removed and the pH of the supernatant is adjusted to 5-5.5 and about 2 volumes of acetone are added and the whole is left overnight.  The precipitate obtained is washed (using acetone, ethanol and ether successively), dried and taken up in 70% aqueous alcohol containing about 10% ammonium acetate, from which a precipitate is obtained by addition of ethanol containing 10% ammonium acetate. The precipitate is dissolved in 0.05M phosphate buffer (pH 7.0) and stirred with diethylaminoethyl cellulose.  The supernatant is acidified to pH 5.4 and passed through a synthetic alumino-silicate gel cation exchanger column from which the active material is subsequently eluted with 40% aqueous ethanol containing 10% ammonium acetate and precipitated by addition of 95% ethanol.  Thereafter, the active material may optionally be further purified by passing an aqueous solution thereof through a "Sephadex" (Registered Trade Mark) column and collecting the first fractions of the effluent.  The product comprises follicular stimulating hormone (FSH) and luteinizing hormone (LH) having an FSH:LH activity ratio of at least 3:1 and has a total gonadotropic activity (determined by the mouse uterus test) of above 80 mg. equivalent I.R.P. per mg.
